Detection method for anti-pinch strip resistance value test equipment

Abstract

The invention discloses a detection method for anti-pinch strip resistance value test equipment. The detection method comprises the following steps: enabling a pushing-down detection piece moving downto be contacted with an anti-pinch strip, when a pressure value which is detected by a force sensor and received by the pushing-down detection piece is higher than or equal to an initial pressure value, recording the current position of the pushing-down detection piece by a detection control circuit, enabling the pushing-down detection piece to act on the anti-pinch strip, thus the resistance value of the anti-pinch strip changes, and acquiring the resistance value of the anti-pinch strip by the detection control circuit by virtue of a detection line; and when the acquired resistance value ishigher than or equal to a resistance value of an end point, recording a corresponding resistance value as well as the current position of the pushing-down detection piece by the detection control circuit. The detection method disclosed by the invention optimizes detection of the anti-pinch strip, and the detection is rapider and safer.

Description

technical field [0001] The invention relates to the field of auto parts testing, in particular to a detection method of an anti-pinch bar resistance value testing device. Background technique [0002] With the development of automobiles, many mid-to-high-end cars are equipped with electric sunroofs, mid-sliding doors, and rear tailgates, which greatly facilitates the operation of opening and closing doors and windows, and provides passengers with a more convenient and comfortable environment. The driving environment, but it also brings potential dangers. That is to say, when a passenger naturally puts his hand on the door frame or sticks his head out of the sunroof, he may be caught by the automatic sliding door or the sunroof and cause injury to the passenger. Therefore, the setting and design of the anti-trap device is particularly important. [0003] As a key safety component, the anti-pinch strip is also widely used in safety systems. Its mechanism of action is to make ...

AI Technical Summary

Problems solved by technology

Now the following problems are found in the detection process of the anti-clamping strip: the pressure block is pressed down to the predetermined stroke, and the force value it receives exceeds the protection program of the detection equipment, causing the equipment to automatically stop and alarm, and no valid data can be detected
